One of the nearby policemen asked Boyle if there was a problem, and she said "Of course there's a f**king problem."

Piers Morgan, one of the judges on Britain's Got Talent and himself a former tabloid editor, today appealed for people to leave Susan alone.

"My heart absolutely bleeds for the poor woman," he said

"Susan is finding it very, very difficult to cope and to stay calm. She's had to read stories and columns, and listen to radio and TV phone-ins, calling her arrogant, insincere, spoiled, fake, mad and so on.

"Susan Boyle has never experienced anything like this and is like a frightened rabbit in headlights. I am calling today for everyone to just give her a break.

"Susan's just a sweet, middle-aged lady from a Scottish village who can't really comprehend the sheer scale of what's happened to her.

"Susan has given new hope and inspiration to a world battered by recession with her voice and her story. Let the increasingly unpleasant bitching and carping stop, right now. Please. She doesn't deserve it," he wrote on his blog.

Despite the furore in Britain, Boyle is still favorite to win the final of "Britain's Got Talent," which takes place on Saturday.

Hollywood star Demi Moore is flying in to London to watch Boyle perform while we can only imagine that Irish promoter and Westlife manager Louis Walsh won't be.

News reports in Britain today quoted Walsh as saying that Boyle was “not a great singer."
